I had unlocked the bootloader of my p768 sometime back by flashing onto a p760 firmware and then i returned back to a nandroid backup of my p768 v20A
With the nandroid restore, I got my old recovery back(the one which is installed by the l9 recovery installer app) and everything normal
I wanted to use the touch recovery which is in this thread.
So i replaced the recovery in my nandroid backup with this one and tried to do an advanced restore of boot.
Now I have a security error.
Isnt the error only locked bootloader specific?
Update--I used the LG flashing application. I had to use the recovery phone option to make it work. It flashed V20A on my phone. When I did the bootloader unlock check in the hidden service menu(3845#*768#) it said "lock"
but now when my phone is in SW Update mode, it says bootloader status:unlocked

Use fastboot to reflash the usual and x from ics. There's a thread with a link if you haven't already downloaded it.

Welcome
I root phone, unlock the bootloader and everything worked nicely. Unfortunately, after restarting the phone only starts ClockworkMod recovery.
I tried to install a new soft CWM 10 of zip and on the same thing, to restore a copy of the original firmware also does not help, always on the LG logo ClockworkMod recovery starts. Is there any possibility to restore the phone back to life?
P.S. Sorry for my english and thx for help.

Please try offline flash again. If your computer cannot detect phone try to update lg usb driver to latest version, I read about this in some thread. If that don't help try to use LG mobile support tool to recovery your phone.

Hi,
I unlocked my bootloader, flashed boot.image and CM snapshot 12 and then after setting up my phone I tried installing TWRP 2.8 with that stupid TWRP Play Store app.
NOW i cannot get into bootloader OR recovery with neither the bootmenu nor adb commandline nor the Volume+- on reboot...
PLEASE HELP me get TWRP 2.8 on my device... OR get me back into Recovery... I'm going crazy here
Turning off the phone and using the volume buttons after turning it on, gives me a black screen with an orange LED for recovery. How do I fix this.
PLEASE, there must be someone out there that can help me get recovery back???

No. Flashing a FTF restores the entire device to a factory state.

Flashing the latest monxDIFIED gives you TWRP 2.8...
Long story - Tried to apply the latest Marshmallow rooted package for D6503 on my 6502 that was already rooted with XZ dual recovery. It installed successfully, was rooted too...but I forgot to add the patch that would fix the radio not working. So I try to reboot to recovery...and that doesn't work anymore. I tried installing TWRP recovery from the manager app, but it wouldn't reboot. Then I ran the XZ recovery installer externally, and now my phone is ****ed. Stuck at an infinite boot loop.
At this stage the only thing I can access is flashtool and fastboot, and since my bootloader is locked I can't flash a recovery that way (nor do I want to permanently lose DRM keys/camera quality as I've heard happens with unlocking the bootloader). I have a memory card and I used the option to disable loading the recovery specified on the XZ thread by adding a 'donotload' file on the sd card.
Still no use - I get a Sony logo for about 5 seconds, the screen goes dark and back to the same. At this point probably my recovery is screwed up or non existent and a bad situation has gone worse with the bootloop.
What can I try now?
@KaiserSnorezay
XZDR is still not compatible with MM, that's why you got a bootloop...
Also you can't install the "regular" TWRP with twrp manager on a LB as there is no recovery partition... it won't work and probably will mess your phone in the process.
The solution is to flash any KK / LP .ftf with flashtool (i would wipe everything when flashing as i have backups of my data/apps) , root it with kingroot or any other method you like, install xzdr for KK/LP and finally reboot to recovery and install the latest MM prerooted rom from niaboc which already has root&recovery (not xzdr btw) included. Since you have D6502 don't forget to install the baseband patch after the rom again
http://forum.xda-developers.com/xperia-z2/development/rom-official-6-0-1-23-5-0-486-beta-t3336770
Just did it exactly this way yesterday on my friends d6503 (minus the d6502 patch obviously) had 0 troubles MM, root and recovery working perfectly.
Thanks, will try this today. Is wiping data required or can i get by by just flashing the older one?

I managed to flash and root 17.1.2.A.0.314, but once again I'm unable to get any damn recovery to work. Installed XZDR, after that TWRP, in both cases it refuses to boot into recovery mode. What am I missing?

Weird, after you have your phone rooted it should be simple to install xzdr... just enable usb debugging in the phone and make sure you have the adb drivers correctly installed in your pc.
Download the latest xzdr from nut's thread ( http://forum.xda-developers.com/showthread.php?t=2261606 ) unzip it and run install.bat . After a successful install the phone should reboot to twrp automatically and it's done.
Okay, I fixed it..using Flashfire! No idea why the recovery didn't work earlier, but now finally I'm on Marshmallow. Thanks for the help!

Try what ptmaniac suggested - flash an older FTF that can be rooted (more recent ones can't), root it, install recovery and then flash the newest build.
You'll have to improve your Google-fu to find a suitable firmware and a root technique for it.

Sorry, I ditched my Z2 for a Oneplus 3 in August 2016. Learnt my lesson, only going to use phones with easily unlockable bootloaders.
I was flashing paranoid android 6.0.2 for my device. I downloaded the zip(from the official paranoid android website) and checked the md5 checksum, which did not match. However, like a total idiot, I flashed it nonetheless. On booting, the phone gets stuck on the boot logo. I tried booting into recovery(TWRP) and performing a factory reset to no avail. I redownloaded the flashable zip for Paranoid, successfully verified the md5 checksum and flashed it again, no avail. Restore a full backup from within TWRP, no avail. My phone still gets stuck on the bootlogo. I have looked all over every forum without any results. Please help me out? I would like to get it back to functional state and flash the rom again. As mentioned, I have access to my custom recovery and can connect to my device via fastboot. I am willing to give any other information you may need.
Thanks!

Flash any 2.X.X ROM. One way is to fastboot flash old stock recovery and flash safest way I think. The other is to flash with twrp make sure after flashing the ROM to flash old twrp IMG after. Make sure you boot right back into twrp.

Assuming you're on OOS3 with TWRP for new bootloader,
- Boot into recovery
- Wipe everything except SD Card
- Flash OOS2 zip
- Boot into it
- Goto settings, unlock dev options, enable advanced reboot
- Then reboot to bootloader
- Flash twrp for old bootloader via fastboot, use this one https://dl.twrp.me/onyx/twrp-3.0.2-0-onyx.img
Done
-Now u hv sucessfully downgraded ur bootloader,flash PA or any supported roms
